Claims. (Cl. 93-37) This application constitutes a division ofnow-pending application Serial No. 221,530 filed September 5, 1962, nowPatent No. 3,135,453 which is a continuation of Serial No. 115,415 filedJune 7, 1961, which was aban cloned in favor of Serial No. 221,530.

This invention relates generally to partitioned or cornpartmentizedcontainers of the character especially adapted to hold a plurality ofarticles or different materials; see for example U.S. Letters Patent toMiessler, Sr., #2940653, dated June 14, 1960.

A primary object of this invention is to provide a novel methodutilizing a one-piece blank construction and comprising the steps forautomatically orienting and posi tioning a partition panel betweenopposite sides of a container or carton when the container is beingerected.

A further object of the present invention is to provide a novel methodof assembling a carton blank to provide a container which, when erected,will incorporate a partition panel aifording adjacent compartments inthe container.

Another object of the invention is to provide a novel method atfordingeconomies in use of material, space used for storage, and a reduction ofmanipulative steps in the assembly of a partitioned container.

Other objects and the nature and advantages of the instant inventionwill be apparent from the following description taken in conjunctionwith the accompanying drawings, wherein:

FIG. 1 is a plan view of a blank used in the invention;

FIG. 2 is a side elevation of the novel blank;

FIG. 3 is a plan view similar to FIG. 1, showing the first step ofassembly of the blank;

FIG. 4 is a side elevation of FIG. 3, illustrating the second step ofassembly of the invention;

FIG. 5 is a view similar to FIG. 4 showing the next step of assembly ofthe blank;

FIG. 6 is a view similar to FIGS. 4 and 5 showing the next manipulativestep of the blank;

FIG. 7 is a side elevation showing the last manipulative step of theblank;

FIG. 8 is a perspective view of the novel folded partitioned container,portions being broken away for the purpose of showing details; and

FIG. 9 is an end perspective view of the partitioned container erectedfrom the condition shown in FIG. 8.

Referring to the drawings in detail, a substantially rectangular blankof paperboard material or the like is indicated generally at 11 andcomprises, in order, a first rectangular end panel 12 hingedly connectedby a fold line 14 to a first side panel 16 which is hingedly connectedby a fold line 18 to a second end panel 26, which is hingedly connectedby a fold line 22 to a second side panel 24. Hingedly connected to theupper marginal edges of the panels 12, 16, 21) and 24, at fold lines 26,28, 3t) and 32, respectively, are top forming flaps 34, 36, 38 and 40,respectively, which are separated by cut lines 42, 44 and 46 which arein alignment with the fold lines 14, 18 and 22, respectively. Hingedlyconnected to the fold lines 48, 50, 52 and 54, at the bottom of therespective panels 12, 16, 20 and 24, are bottom forming flaps 56, 58, 60and 62, respectively. The bottom forming flaps 56,

3,185,648 Patented May 25, 1965 58, 60 and 62, are separated by cutlines 63, 64 and 65, which are respectively in alignment with the foldlines 14, 18 and 22.

Hingedly connected by a fold line 66 at the side margin of the secondside panel 24 is a panel including a container-glue flap 67, theopposite ends 68 and 70 of which are tapered slightly away from the foldlines 32 and 54 to dispose the glue flap below the upper and lowermargins of the assembled container.

Hingedly connected by a line of separation or foldable tear line 72 is afirst partition glue flap 74 extending the length of one margin of arectangular partition panel 76 and being hingedly connected thereto by afold line 78-. Hingedly connected at the opposite side margin of thepartition panel 76 at a fold line 80 is a second partition glue flap 82.

The inner surface 84 of the partition glue flap 82 will have depositedthereon a layer of suitable adhesive material by means of automaticgluing apparatus; see FIG. 1. After this has been accomplished, thepartition panel and partition glue flap 74 are folded along the tearablefold lines 72 into juxtaposed relation on the second side panel 24 inthe manner shown in FIGS. 3 and 4. After this has been accomplished,glue is applied to the exposed sides of the container glue flap 67 andfirst partition glue flap 74 which are disposed in juxtaposition, asseen in FIGS. 3 and 4. The glue can be deposited, for example, by meansof a conventional, lower glue pot-and-wheel 38 and an upper, gluebottle-and-wheel 86 as seen diagrammatically in FIG. 4, or any othersuitable means may be utilized.

After glue has been disposed on opposite sides or outer exposed surfacesof the glue flaps 67, 74, the panel 24, with the partition panel 7 6attached thereto, is folded into overlying relationship with respect tothe second end panel 20 disposing the glue-applied surface of the glueflap 74 onto an intermediate portion of the first side panel 16, seeFIG. 5. After this has been accomplished, the first end panel 12 isfolded on the hinge line 14 toward the exposed surface of the glue flap67 of the container and the marginal edge 90 of the first end panel willbe secured in overlying relationship to the container glue flap 67.

It will be noted that the side panels 16 and 24 are of the samedimensions, and the end panels 12 and 20 and the partition panel 76 areof an equal Width.

As seen in FIG. 6, the assembled carton is illustrated; however, thetear line 72 is not severed at this time.

The assembled position of the parts is shown in FIG. 7. When the firstand second side panels 16 and 24 are disposed in parallel relationship,and the end panels are also disposed in parallel relationship to form arectangular container, the tear line 72 will be severed, and thepartition panel 76 Will move to a parallel position with respect to theend panels 12 and 26, see FIGS. 7 and 9. After this has beenaccomplished, the top and bottom flaps 34- 40 and 56-62 may be orientedinto their proper position.

Thus it will be noted that through the expedient of constructing asingle unitary blank of the character described, a partition panel isprovided which is oriented into its proper position of assembly duringthe erection of the container, this expedient requiring no specialmanipulative steps, and merely involving a single one-piece blank ratherthan separate parts comprising the container per se and the partitionper se.

It will be obvious to those skilled in the art that various changes maybe made without departing from the spirit of the invention and thereforethe invention is not limited to what is shown in the drawings anddescribed in the specification but only as indicated in the appendedclaims.
